Despite far-reaching plans for the tegel airport area, it is not clear to what extent the ground is contaminated with pollutants. It also remains to be seen whether there are still dormant deposits underground. "Statements on soil contamination can only be made once the site has been put into operation and is freely accessible for investigations," finance secretary jens spahn (cdu) responded to a question from the fdp in the bundestag.
Fdp member of parliament christoph meyer said of spahn’s rearances: "this shows that on the federal and senate sides they don’t know exactly what costs the state will still have to bear. This is completely a black box for all of us."The fdp has been campaigning for years not to close tegel. It is clear to everyone that after decades of flight operations, considerable ground pollution is to be expected, meyer said.
The explosive ordnance has been removed from parts of the site so that aircraft can take off and land safely. According to the paper, however, it is not yet possible to say whether the flat is also suitable for apartments. Tegel airport is to close when the new capital airport in schonefeld comes on stream. As things stand at present, this is planned for october 2020. The 460-hectare site in tegel will then be home to a research and business park and apartments.
159 hectares of the site belong to berlin, 302 hectares to the federal government. Potential pollutants include aviation fuel kerosene and ammonium from deicing agents. Even the senate does not yet have an overall view of the situation. The airport company has already removed many individual contaminated sites. However, historical studies and soil samples also pointed to gross potential risks, according to a response from the city’s development administration to an fdp question last summer. The floor of the planned schumacher quarter residential area will probably have to be replaced.
According to the airport company, it has set aside around two million euros to clean up the legacy of the 1970s – when construction of the terminal began. Costs for contamination from the time before had to be borne by the state. After the second world war, the site was filled with two to four meters of rubble in many places. Previously, the area had been used as a push site, airship harbor, rocket and troop support area.
In the official information on the referendum on the closure of tegel last year, the contaminated sites did not play a role. In the non-binding decision, a majority supported keeping the airport in operation in parallel with ber.
